小编Ric*_*ick的帖子

我在iphone的stackoverflow上找到各种电话号码验证,但似乎都没有验证它们似乎只是改变了格式.示例电话号码格式.

目标:通过警报输入此号码.北美人有或没有破折号.

所以有一些代码,但每一件事都是无效的任何想法.

- (void)textFieldDidEndEditing:(UITextField *)textField {

NSString *str=@"^\\+(?:[0-9] ?){6,14}[0-9]$";
NSPredicate *no=[NSPredicate predicateWithFormat:@"SELF MATCHES %@",str];
if([no evaluateWithObject:textField.text]==NO)
   { 

       UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Warning" message:@"Please Enter correct contact no." delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil];

       [alert show];
       [alert release];

   }
   else{
NSString *textValue = textField.text;
NSLog(@"Value: %@", textValue);
   }
}

所以我创建了一个按钮.我希望它有圆角而没有制作圆形.png文件我可以设置背景图像.我可以绕过角落.但是,当我设置背景图像时,圆角会消失.

我很久以前就这样做了一次,但似乎无法让它恢复正常.如何才能做到这一点？

UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];
[button1 addTarget:self action:@selector(goSpecials)
  forControlEvents:UIControlEventTouchUpInside];
[button1 setTitle:@"Specials" forState:UIControlStateNormal];
button1.titleLabel.font = [UIFont fontWithName:@"Arial-BoldMT" size:(15.0)];
[button1 setTitleColor:[self colorWithHexString:buttonColor] forState:UIControlStateNormal];
button1.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed: @"button.png"]]; 
 //[button1 setBackgroundImage:[UIImage imageNamed:@"button.png"] forState:UIControlStateNormal];
button1.frame = CGRectMake(20.0, 232.0, 135.0, 32.0);
button1.layer.borderColor = [UIColor blackColor].CGColor;
button1.layer.borderWidth = 0.5f;
button1.layer.cornerRadius = 8.0f;
[self.view addSubview:button1];

button.png:

我需要在使用webview时从隐藏的div标签中提取值.我在我的webview活动中打开了javascript但不喜欢"".我如何实现目标？

public class buttonOne extends Activity{

 WebView wb = null;

 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.buttons);
  wb = new WebView(this);
  wb.getSettings().setJavaScriptEnabled(true);
  wb.setWebViewClient(new HelloWebViewClient());
  wb.getSettings().setJavaScriptEnabled(true);
  wb.loadUrl("http://ishopstark.com/mobileapp.php?category=1");
  setContentView(wb);

 }

 private class HelloWebViewClient extends WebViewClient {

  public boolean shouldOverrideUrlLoading(WebView view, String url) {
   view.loadUrl(url);
   <script type="text/javascript">
     {
        var varSendText = document.getElementById("sendtextcoupon").value;  
     }
     </script>

   return true;
  }
 }

我有一个视图控制的应用程序.在我的xib上我没有webview,但我确实有按钮可以调出带有webview的类.所以按下按钮一,然后弹出一个uiwebview,等等.

现在在我的一个课程中,我拉出一个有链接的远程网页.我想用shouldStartLoadwithrequest覆盖那个按钮链接.从来没有像现在这样被称呼.

现在我的班叫做Tenth.m,我的视图控制器中有这个代码

- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {

NSLog(@" Test spot 1");
NSString* scheme = [[request URL] scheme];
if ([@"didTap" isEqual:scheme]) {
    // Call your method
     NSLog(@" Test spot 2");
    [self didTapButton1];
    return NO;
} else {
     NSLog(@" Test spot 3");
    return YES;
}}

但我什么都没得到(我的NSLog都没有).我已经尝试将它放入我的Tenth.m课程中,但仍然没有.我查看了其他示例,甚至下载了一个但它只使用了viewcontroller和delegates类.没有第三类.

我迷失了为什么它没有被召唤.

这是我的第三堂课

#import "Tenth.h"


@implementation Tenth

- (void)awakeFromNib
{
[category10 loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.mywebsite.com/api/didtap.php"]]];

}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization
}
return self;
} …

嗨,我正在使用android,我正试图在这个类周围放一个"if"语句但是我得到错误"令牌上的语法错误"如果",无效的AnnotationName"任何帮助？

    private String str = "0"; 
if(str == 0){
     public boolean onKeyDown(int keyCode, KeyEvent event)
     {

         //Handle the back button
         if(keyCode == KeyEvent.KEYCODE_BACK)
         {
             //Ask the user if they want to quit
             new AlertDialog.Builder(this)
             .setIcon(android.R.drawable.ic_dialog_alert)
             .setTitle("Coupon")
             .setMessage("Do you want a coupon texted to you?")
             .setPositiveButton("YES!", new DialogInterface.OnClickListener()
             {
                 @Override
                 public void onClick(DialogInterface dialog, int which)
                 {
                     //Stop the activity
                     Toast.makeText(buttonOne.this, "Great! You'll get one in just a couple of minutes.", Toast.LENGTH_LONG).show(); 
                     finish();
                 }
             })
             .setNegativeButton("Not now", new DialogInterface.OnClickListener()
             {
                 @Override …

在我的webview中,我将 通过Android浏览器将其视为移动网站http://www.nsopw.gov/Core/OffenderSearchCriteria.aspx.

但是在我的webview应用程序中,它被视为不是移动浏览器,因此没有被重定向到移动版本.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.buttons);
    wb = new WebView(this);
    wb.getSettings().setJavaScriptEnabled(true);
    wb.setWebViewClient(new HelloWebViewClient());
    wb.getSettings().setSupportZoom(true);
    wb.getSettings().setBuiltInZoomControls(true);
    wb.getSettings().setDomStorageEnabled(true);
    String[] loading = getResources().getStringArray(R.array.array_loading);

    Random r = new Random();
    int rN = r.nextInt(12 - 1) + 1;
    progressBar = ProgressDialog.show(Sex_Offenders.this, loading[rN],
            "Loading...");

     final String urlToLoad ="http://www.nsopw.gov/Core/OffenderSearchCriteria.aspx";
    //final String urlToLoad = "http://m.familywatchdog.us/m_v2/msa.asp?es=&l=0&w=0&brtp=html&rstp=xlarge&imgtp=jpg&imgw=310&imgh=320";

    wb.setWebViewClient(new HelloWebViewClient() {
        public void onPageFinished(WebView view, String url) {

            if (progressBar.isShowing()) {
                progressBar.dismiss();
            }
        }
    });

    Context context = getApplicationContext();
    if (Repeatables.isNetworkAvailable(context) == true) { …
